Yum Woon Sen is a type of Thai salad made with clear bean vermicelli, or Glass Noodles. The ingredients are quite easy to obtain, and it just takes a few minutes to put together as a beautiful lunch or as part of a meal. In addition to the noodles, this recipe includes juicy shrimp, ground pork, Chinese celery, mushrooms, onions, shallots, and hot chili, but you can vary the ingredients as much as you want. The important part is the seasoning, which comes from a simple, fresh, and clean tasting dressing made with lime juice, fish sauce, and sugar. Yum Woon Sen, like many Thai foods, is expected to have a balance of sweet, spicy, salty, and sour flavors. However, this salad is completely delicious even if you choose to leave the hot chili out.
